MINNEAPOLIS - Only two of the sextuplets born to a Minnesota couple were still alive Monday, and both remained in critical condition, hospital officials said.

The fourth sextuplet to die, Cadence Alana Morrison, died Saturday morning, officials at Children’s Hospital in Minneapolis said. Three of her brothers died within the first week of their June 10 birth.

Parents Ryan and Brianna Morrison of St. Louis Park released a statement through the hospital saying: “Though our difficult time continues, our faith remains strong. Our families, friends, and churches have provided us with great comfort, for which we are deeply grateful.”
